Unparalleled tunneling detection and location capability

Seismic Acoustic Detection and Ranging Border Tunneling Detection Technology

Quantum’s newest product, seismic-acoustic detection and ranging, SADAR® is proven to be a ground breaking tunneling detection and location capability. Not only can subsurface activity be located, but the source of energy can be classified as well. This is done using seismic acoustic detection and ranging border tunneling detection technology.

Our tunneling systems localize tunneling activity and automatically generate alert message information when a signal of interest is detected. In operation, a SADAR® system automatically and in real-time detects, classifies, and localizes tunneling activity and usage.
